LG OLED B3 65" vs Samsung S90C 65" (4K OLED)
The Verdict
Both 65-inch OLEDs deliver stunning visuals, but they cater to different priorities. LG's B3 uses WOLED technology with 600-nit peak brightness and webOS 23, offering excellent contrast and a user-friendly smart interface at $1299. Samsung's S90C employs superior QD-OLED tech with 1500-nit brightness, enabling dramatically better HDR performance and superior gaming features like 144Hz support,though it commands a $700 premium. The S90C excels in picture quality, gaming performance (6ms input lag vs 7ms), and audio (40W vs 20W), while the B3 provides exceptional value for mainstream viewers. Choose the LG for budget-conscious buyers seeking great picture quality; opt for the Samsung if you're a serious gamer or cinephile demanding peak brightness and the latest display technology.
